Page 6: Description & Principle Of Operation
Description & Principle of Operation DeScRiPtion SEC-1223BBM is a Switch Mode Power Supply (SMPS), which converts 120 VAC, 50/60 Hz to regulated 13.8VDC at 23A continuous. It has additional provision for battery backup with charging in conjunction with external 12V Lead Acid Battery. -

SeCtIOn 3 | Description & Principle of Operation • Cooling by temperature controlled fan improves efficiency and prolongs life of the fan • UL safety listed as “Information Technology Equipment Power Supply” for USA (UL Standard ANSI/UL-60950-1) and for Canada (CSA Standard CAN/CSA-C22.2 No. 60950-1) • Complies with FCC Part 15(B), Class B for limits on conducted and radiated Electromag- netic Interference (EMI) PRinciPLe oF oPeRAtion Please refer to the Layout at fig. 2.1. The unit consists of 2 Sections - Switch Mode Power Supply (SMPS) Section and Battery Backup and Charging Section. -
Page 8: Protections
SeCtIOn 3 | Description & Principle of Operation note: the fan may not switch on at all in case of low loads or in colder ambient temperatures because the temperature of the transformer windings may not rise to threshold of ≥ 60°c ± 5°c / 140°F ± 9°F under these conditions. In case the fan fails or if the cooling is not adequate due to higher ambient tempera- ture, inadequate air circulation or blockage of ventilation openings, the temperature of the transformer windings will rise. -

SeCtIOn 4 | Protections Battery Backup Function is Used - external Battery is connected If the load tries to draw current higher than the current limit value of 25A of the Power Supply Section, the output voltage of the Power Supply Section will not be regulated and the voltage at the Load Terminals (3, 4) will drop. -

SeCtIOn 4 | Protections In case the fan fails or if cooling is not adequate due to higher ambient temperature or inadequate air circulation or blockage of air ventilation openings, the temperature of the output power transformer windings will rise and at temperature ≥ 105°C ± 5°C / 221°f ±... - Page 11 SeCtIOn 5 | Installation After crimping the Terminal Lugs, use insulating heat shrink tubing or tape to insulate the bare cylindrical portion of the lug. Load connection: The load is connected to the terminals marked “Load +” (4) and “Load - ” (3) through 32V, 25A fuse (f2) (See details below under heading “External fuses”).
- Page 12 SeCtIOn 5 | Installation resistance). Excessive voltage drop across the length of wires connecting the power source to the load produces excessive power loss and may also shut down the load due to under voltage created at the load end. Hence, the voltage drop should be kept to the minimum at around 2% by using thicker wires for longer distances.

SeCtIOn 6 | Operation Please refer to fig 2.1, page 5 - Layout & output Connections. cAUtion! If AC input power is not available and a battery has been connected for backup function, the load will be powered by the battery and the battery will continue to discharge as long as the load is in oN condition. - Page 14 SeCtIOn 6 | Operation cHARGinG AnD BAcKUP oPeRAtion Charging current will be proportional to the discharged state of the battery and is lim- ited to maximum of 4A when the battery is completely discharged (Standing Voltage of 11.4V). The current will taper down from 4A as the battery gets charged and its voltage rises.

In North America, the applicable standard is fCC Part 15(B) for Class “B” Digital Devices for residential Installations. The corresponding European standard is EN55022, Class “B”... - Page 16 SeCtIOn 7 | limiting electro-Magnetic Interference (eMI) Then, if necessary, relocate either the antenna or the power supply farther apart. The receiver may “hear” the power supply. A slowly moving, slightly buzzing carrier heard in the receiver may be caused by the antenna being too close. As with the transmitter related noise pick up, a loose coaxial connector or a broken or a missing ground may aggravate this problem.
- Page 17 SeCtIOn 7 | limiting electro-Magnetic Interference (eMI) proportional to the person’s skin resistance will flow through the person’s body to Earth Ground. The leakage current through the body is higher when the skin contact resist- ance is lower i.e. if the skin is wet or wounded. This leakage current does not return to the power source but is dissipated in Earth Ground.
